PATENT TAKE-UP MCHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 397,086, dated January29, 1889.

Application tiled April 30, 1888. Serial No. 272,294. (No model.)

To all nih/m t may con/cern.:

Be it known that I, lVlLLIAM J. LUTTON, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Take-Up Mechanism.

for Looms and I do hereby declare that the following' is a full, clear,and exact description thereot', which, in connection with the drawingsmaking a part of this speeilication, willI enable others skilled in theart to which my invention belongs to make and use the same.

Myinvention relates to looms, and more particularly to a take-upmechanism for looms using a spring-reed. The object of my invention isto provide a mechanism by which, even in very delicate weaving, thespeed of the take-np roll can be governed by the texture oi' the goodswoven, the variation being regulated by the movement of the spring-reedin beating up, in the manner to be hereinafter :fully described.

Referring` to the drawings, Figure 1 represents a section ot' a loom towhich my .improvements are applied, the section being taken just insideone loom side and looking toward the other; and Fig. 2 represents adetail view, looking from the right in Fig. 1.

In the aecompanyii-ig drawings, 1 is a portion ot' the loom-side; 2, thebreast-beam; 3, the crank-shaft, and 4 the lay. llolted to the horns 5ot the lay are stands G, one on each end, to which is pivoted, at 7, theswinging frame S, in which the reed 9 is carried.

On the back side otl the lay-sword 10, at 11, is pivoted a lever, 12,the upper end of which bears against the lower part of the swingingreed-frame 8, being kept in contact with said frame by the iiat spring13, the upper end of which engages the upper end of the lever 12 and thelower end ot' which is bolted to the lay-sword at 14. As usuallyconstructed the iiat spring 13 bears directly on the swinging reed-frame3 without the intervention of the lever 12, and this is the case in myconstruction on the opposite end of the lay. An adjustable hook-bolt,15, passes through the lay-sword 10 and connes the spring 13, said bolt15 being held in position to give the required tension on said spring'13 by means of the nut 16. The lower end of lever 12 has a slot, 17,therein, in which is confined, by means of a Hat shank and nut, the stud18, through which is threaded the set-screw 19, held in any desiredposition by the check-nut 20.

On a stud, 21, fast in the loom-side, is pivoted the lower end of alever, 22, which is provided with a flange, 23, opposite the slot 17 in.lever 12, against which liange the end of 6o set-screw 19 may strikewhen the lay-sword 10 and the lever are swung into proper position. Aspiral spring, 24, acts upon the upper end of the lever 22, one end ofsaid spring' being secured thereto and the other end connected to aneyebolt, 25, which passes through an ear, 26, cast on the loom-side, andis held by a thumb-nut, 27, by means of which the tension of the spring24 may be regulated. An adjustable hook, 28, passes through the 7olay-sword 10 and is fastened by a set-screw, 29. ASaid hook 23 isadapted to engage the lever 22 on the opposite side from the setscrew19.

Fast to the loom-side is a stand, 50, carrying two hubs, 51 and 52,through which slides a rod, 53, provided with a head, 54, on its forwardend. The stand 50 is so made that the center of rod 53 comes in linewith the cen-v ter of lever Confined by set-screw on the 8o rod 53 is acollar, 55, between which and hub 51 is a coil-spring, 56, on the rod53. On the rear end of rod 53 is a collar, 57, confined by a setserew.By means of the two collars 55 and 57 the tension of the spring 56, andalso 85 the distance which the head 54 projects from the stand 50, maybe adjusted.

lTo the upper end of the lever 22 is pivoted an arm, 30, carrying apawl, 31, on its outer free end, which engages the teeth of the 9oratchet-wheel 32, mounted on a stud, 33, fast in the take-uproll stand34.

On the hub of the ratchet-wheel 32 is secured a pinion, 35, whichengages an intermediate pinion, 36, also mounted on a stud fast in thetakeup-roll stand 34. The pinion 3U meshes with the gear 37, fast on theend of the shaft 33, on which is fastened the take-up roll 39. Thetake-up roll 39 is of the proper length to receive the width of thegoods deroo sired to be woven, and the shaft 33, upon which said roll 39is mounted, projects from each end thereof, and is supported in twostands, 34, secured to the loom-side, the gearing l'or operating thetake-np roll being pl aeed outside the stands fil.

'Upon the upper ends of stands Si are hubs -L0, into which are screwedrods 4.1,whiehprojeetimt under the lay -land are l'astened in anydesired position by a cheek-nut, ft2. The length of the rods ll is sueh,and they are so plaeed, that when the lay beats up the projecting pointsengage the springs .l ."l and push them ont of eontaet with lever ,l2and reedtrame S adistanee determined by the adjustment ol. rod -Ll Ainits supporting-hub il) on stamfl Sl-l. 'lhe lever has a bend or eu'rvein it at a point, 455,110 allow the rod -l-l to pass by it and engagethe spring i3.

'.lhe dotted lines -l-l represent the lines ol' warp with the shed o}m,and represents the eloth passing over the breast beam 2 around thetake-up roll 235i, and to the elothwinding roll ld, whieh is driven inthe usual manner by gearing :trom the take-up roll, the gears beingplaeed on the opposite end. ot the talCe-i'lp-roll shafts .trom thetrain ot gearing 255, 23H, and 37.

From the above description, in eonneetion with the drawings, theoperation ot' my im,- proved take-up meehanism will. be readilyunderstood by those skilled in the art, and isas .t' ol lows 'lheseveral parts being in the position shown in the drawings, the shuttleis thrown, laying a shot ot lilling in the shed, and the lay beats up.'\\'hen the lay gets nearly up, and bet'ore the .filling begins to meetappreeiable resistance in going into the eloth7 the projeeting ends ot'the rods ll engage the springs l Il and lrelieve the reed-trame S andthe lever 12 ot their pressure.

The adjustable hook 2S, which determines the position Vin which thelever 22 is leltr by the lay, and the set-screw lf) are so plaeed thatabout the time the rods ll engage the springs l2) the point ol' theset-screw lt) engages the liange 23 on lever 22, bringing the tension olthe spiral spring Q-l to bear on the reed-tranne 8 through lever l2. lhespring 2l is adjusted by thumb-nut 27 tothe desired tension, regulatingthe amount which the reed-frame sprin lbaek in beating the illing intothe eloth to the desired texture. The more the reed springs back thefarther the point ot' set-screw 19 throws the lever 22 torward, and themore teeth are taken by pawl l on the ratchet-wheel. 32. lVhen. the laygoes back, the lever .is pushed or drawn by hook :28 over to the samepoint everytime, turning the take-np roll iid, through the train ot'gearing E55, Sie, and $37, an amount proportioned to the sjfiring of thereed. 'lhe throw ot' the pawl 23]. may be further regulated by theposition ot the set-serew l?) in the slot i7 in the lever l2, the movingot' it down inereasing the throw of the pawl .tor the same movement ot'the reed.

It will be observed that the pressure ol' springs 13 is taken oli thereed. by the rods 441 justy as the pressure of springl 2st is applied..lhe reason :t'or this is, that a pressure ot. the reei'l-.t'rame whichlis sulieient to hold the reed up rigid for the passage ot' the shuttlewhile the lay is passing the baek eenter is not delicate enough on somegoodsto weigh the resistanee of the Ylilling going into the eloth.

A tritling tremor ol theretal while the shuttle is passing is sutiieientto eause it to miss goin squarely into thebox'.

The purpose of the spring-rod 53 isto serve as a stop [for the lever toprevent .its being drawn by spring il, or otherwise, beyond the pointtowhieh it.- Vis earried by hook. 2S, the rod 523 being adjusted so thatits head 54: engages lever 22 just as hooi; 2S eea-ses to push lever 22baelC. The spring 5U is ot su iteien t strength to prevent moving ollever 22 by spring 24 imlependent ot the aetiou ot' t-he hook 2S. Theparts are usually so adjusted. that spring 5V does not aet, `i t merelypreventing breakage in ease ot imperteet adjustment.

Usually the tension of the goods being woven over the take-up rolls issut'tieient to hold lever 22 at the point to whieh it is pushed. by hook2S, and the spring-rod 53 might be dispensed with, except in very lightwork.

It will. be understood that the details of'eonstrueti on ot the severalparts ot' my improved take-up mechanism. may be varied somewhat troniwhat is shown and deseribed, it desired, without depz'irting from theprinciple ot' my invention.

Ilavingthns deseribed my invention, what I elaim as new, and desire toseenre by lietters Patent, is-
